Play Selection by Down

Posted on by | Leave a reply

plot of chunk plot-play-by-down

Continuing with the newly available football data (new link) and inspired by a question from Drew Conway I decided to look at play selection based on down by the Giants for the past 10 years.

Visually, we see that until 2011 the Giants preferred to run on first and second down.  Third down is usually a do-or-die down so passes will dominate on third-and-long.  The grey vertical lines mark Super Bowls XLII and XLVI.

Class Photo

About a month ago we had our final Data Science class of the semester.  We took a great class photo that I meant to share then but am just getting to it now.

I also snapped a great shot of Adam Obeng in front of an NYC Data Mafia slide during his class presentation.

Eli Manning’s Receiver Preference by Down

plot of chunk make-graph

With the recent availability (new link) of play-by-play NFL data I got to analyzing my favorite team, the New York Giants with some very hasty EDA.

From the above graph you can see that on 1st down Eli preferred to throw to Hakim Nicks and on 2nd and 3rd downs he slightly favored Victor Cruz.

The code for the analysis is after the break.

Ringing Bells in Myanmar

While President Obama made big news for his trip to Myanmar I would like to point out I rang the same bell as him (picture above) three years before he did.

More Lotto Statistics

Posted on by | Leave a reply

Thanks to Rachel Schutt, who I’m teaching with at Columbia, and Cathy O’Neil from MathBabe I had the opportunity to go on TV and talk about the statistics of tonight’s Powerball lottery.

There’s an article with a brief quote from me and a video where I may a very quick appearance at the 1:14 mark.  My interview during the live broadcast actually went on for about three minutes but I can’t find that online.  If I can transfer the video from my DVR, I’ll post that too.

In the longer interview I discussed the probability of winning and the expected value of a given ticket and other such statistical nuggets.  In particular I broke down how choosing numbers based on birthdays eliminates any number higher than 31 mean you are missing out on 28 of the 59 possible numbers that are uniformly distributed.  Hopefully I’ll find that longer cut.

The video can be found here:  Video

Yankees and Republicans

Posted on by | Leave a reply

A friend of mine has told me on numerous occasions that since 1960 the Yankees have not won a World Series while a Republican was President.  Upon hearing this my Republican friends (both Yankee and Red Sox fans) turn incredulous and say that this is ridiculous.  So I decided to investigate.  To be clear this is in no way shows causality, but just checks the numbers.

The data was easily attainable so it really came down to plotting.

The plot above shows every Yankee win (and loss) since 1960 and the party of the President at the time.  It is clear to see that all nine Yankees World Series wins came while a Democrat inhabited the White House.  The fluctuation plot below shows Yankee wins both before and after 1960 and the complete lack of a block for Republican/Post-1960 simply makes the case.

There are similar plots for the American League after the jump.
